Discharge nozzles shall be provided with caps or other suitable devices to prevent entrance of contaminants. Which option is most consistent with this requirement?

• A. Caps
• B. Hinges
• C. Bolts
• D. Clamps

Answer: (A)

Caps provide a seal for discharge nozzles to prevent contaminants from entering when the system is idle. Keeping dust, moisture, cooking residues, and other debris out of the nozzle preserves a clear, unobstructed discharge path and helps ensure reliable operation when the system is activated. Hinges, bolts, and clamps by themselves don’t seal the opening and won’t prevent contaminant entry, so they don’t fulfill the same protective function. Therefore, caps are the appropriate choice to meet this requirement.
